able Tire for the .lVheels of Gun-Carriages set forth in thefollowingspecification. I

This invention has forits object'topro- .vule an improved removable.tlre or ,auxll- ,iary tread for the wheels of gun; carriages and othervehicles, designed .to increase .the

. bearing area ofthewheels on soft ground.

The improved tire or tread consistsvin a known manner of a series ofelements-or sec tions surrounding the rim oftheewheeland arranged .end ito end against one another, these elements being fixed around the tireby means of clips placed between the spokes of the wheel.

The essential characteristic feature of the improved tire or treadconsists in this that its elements or sections are constituted each by aseries of ratans, arranged side by side and curved to the form ofsectors concentric to the wheels, these ratans being fixed at their endsin molded or forged members on which the attaching clips are pivotallymounted.

In a practical constructional form of this invention, the ratans fixedin the molded or forged members, are also connected together by atransverse plaiting of osiers, wire, or other suitable flexiblematerial. The elements of the improved tire may be protected by a casingof sheet steel or other metal which may be attached to the plaiting forconnecting the ratans together by sewing with wire. a

Two constructional examples of the invention are illustrated. in theaccompanying drawings in which Figure 1 is a side elevation partly insection-of a vehicle wheel provided with a tire according to thisinvention. y

Fig. 2 is a view of an element of the improved tire, drawn to a largerscale, half in side elevation and'half in section on the line II--II ofFig. 3, which latter figure is a cross section on the line III-III ofFig. 2.

Fig. 4 is a section on the line IVIV of Fig. 2.

Fig. 5 is a half plan corresponding to the side elevation shown in Fig.2.

These members, whicli; are'- suitably curved 1 'in -thetransversevdirection, form a vkind of :box or casingihavingmortises equal ;in num-:ber .to:the ratans A. J This number; i such that .when theigtireelement .is inpoeition- .on the wheel, it will. .proj eat I appreciablybeyond both I sidesnof-thelwheel rim .B-In -.practice ,the continuityofthe tive an :also .its suppleness (are assugediby connecting 70 rth'erra'tanstogetherjby .meansof a plait E I .prefei rably of osiers.{Elie transverse-Plait may be completed by longitudinal thin rods F ofosier or other devices which may be fixed to the transverse plaiting Eby means of nails f.

The clips for fastening together the tire elements may, as shown in thedrawings, .be constituted as follows The ends of the molded or forgedmembers B and C are formed with lugs B B, and C respectively. To theselugs are ivoted links G and H. One of the links namely the link G,carries the pivot pin i of a connector such as I, by means of which theclip is closed by connecting the two links together. The connector I maybe a pivoted bolt of the usual construction. In the example shown thefree end of the link H constitutes a bearing for the reception of thefree end of the connector I. This connector has a screwthreaded end I onwhich there is screwed a nut I carrying a perforated disk I so that thenut' can be locked by means of a pin h engaged in lugs on the links H.The nut I may have a shoulder 71 which engages under a nose h on thelink II when the locking has been effected.

As shown in the modification shown in protected by a sheet metalsheathing or casing. This casing may be made in two parts, namely thetread member J inclosing the outer surface ofthe tire and its edges, andthe backing member K, of less thickness, inclosing the greater portionof the inner surface of the tire. The parts J and K may be connectedtogether and fastened to the tire element proper by sewing by means ofwires L. The assemblage may be completed by small bolts M which areengaged in the edges of the sheet metal part J and pass between theratans A, and are secured by nuts m.

What Iclaim is 1. An auxiliary wheel-tread comprising a plurality oflongitudinally disposed ratans plaited with transverse oslers, and meansfor a series of removable sections ada ted to be 7 arranged around theperiphery 0 a wheel, said sections having a width greater than that ofthe permanent tread of the attached wheel to increase the ground-bearingsurface of such wheel, each section comprising a flexible bodyandstifiening casings at its ends projecting beyond the sides of theattached wheel. to support the edges of the flexible body projectingbeyond the sides of the wheel, and means for detachabl securing thesection to the periphery o the wheel.

4. An auxiliary wheel-tread comprising a plurality of longitudinallydisposed ratans plaited with transverse flexible members, and means forsecuring the tread to the periphery of the wheel.

5. An auxiliary wheel-tread consisting of a series of removable sectionsadapted to be arranged around the periphery of a wheel, saidsections-having a width greater than that of the permanent tread of theattached wheel to increase the ground-bearing surface of such wheel,each section comprising a plurality of longitudinally disposed ratansplaited with transverse flexible members, a stiff casing at'each end ofthe section engaging the ends of the ratans to hold the latter in place,said casing projecting at its ends beyond the sides of the attachedwheel to support the projecting edges of the section, and means fordetachably securing the sections to the periphery of the wheel.

In-testimony whereof I have signed this specification.

EUGENE SCHNEIDER.
